ILER MECHANISM.

Application filed June 3,

My invention relates to improvements in coiler mechanisms for ceiling and packing cotton and other libres in cans of carding, cor-.rhin and drawing machines and the ob- ',icct of invention is to provide means whereby the pressure exerted by the Asliver while it is being coiled and packed into the cans may be regulated.

ln prior machines of the class above noted, the inclined sliver coiler tube has been constructed integral with its motion transmitting gear, consequently the pressure of the combined weight which is imparted to the coils or layers of sliver in a full can is the same whether the sliver is coarse or fine. By this constructionj especially in working tine sliver7 the sliver ispacked in the can so tightly that when the full can is removed from the machine the elasticity of the packed layers causes them to spring up in the can and if the operative does not use due care they topple over onto the floor causing waste due to breakage and soiling of the sliver. My invention obviates this objectionable feature.

TWhile in the accompanying drawings my improvement is shown as applied to a drawing machine, it is obvious that it may be' arranged to cooperate with other machines of the saine nature.

ln the drawings Figure 1 is a sectional elevation on line 1-1 of Figure 2 of the sliver' coiling mechanism applied to a drawing machine showing my improved construction thereon. Figure 2 is a plan view showing the coiler tube gear and its relation to the can-full stop motion. Figure 3 is an enlarged sectional elevation on line '3--3 of Figure showing my preferred form of pressure regulator. Figure e is a plan view of a portion of the coiler tube gear showing my improved pressure regulating means applied thereto.

The sliver calender rolls, the can-full stop motion and the mechanism for supporting and revolving the sliver receptacle are here shown substantially the saine as now in common use in drawing machines. y

Having reference to the drawings, 10 is the coiler plate fixedly connected to the framing 11 of the machine, 12 is a ring gear rotatively mounted in the circular bearings 18 cut in the upper surface of the coiler plate 10. The lower part of the ring gear 1926. Serial No. 113,457.

12 is provided with an inner annular flange 14 whose edge coincides with the edge of a circular opening 15 in the coiler plate 10. rihe flange lei serves as support for the rim of the coiler tube disk 16 which is loosely mounted thereon and prevented from twisting around on its seat by a pin 1'? fixed to the ring gear and coacting with a notch 18 cut in the rim of the coiler tube disk. The bottom of the disk 16 loosely fits in the circular opening 15 of the coiler plate 10, the lower surfaces of both disk and plate being flush with each other normally.

The disk 16 carries the inclined tube 19 the mouth of which is directly beneath the .delivery of the calender rolls 20, the sliver therefrom passes through the tube and is laid in acoil formation in the slowly rotating can 21 whose axis of rotation is slightly offset from the axis of rotation of the coiler tube disk.

Rotation is imparted to the coiler tube disk through its connection with the ring gear the teeth of which meshes with a spur gear on the upright shaft 23 which in turn is rotated by bevel gear connections with the power transmitting shaft 24 common to machines` of this class. The rotation of the sliver can 21 is effected by suitabie gearing between the can-table 25 and the shaft 23. l

.In operation as the can becomes full the layers of sliver 2G pressing against the underside of the disk pack the sliver in the can until the pressure of the mass of fibre is sufficient to overcome the weight of the disk and pushes it upwards from its seat into contact with the detector lever 37 which is a member of the customary form of canfull stop motion, a fragmentary view of which is shown in Figures 1 and 2, thus stopping` the machine.

It is obvious that the lighter the weight of the disk, the less force or pressure need Vbe exerted by the packed sliver to effect the stoppage of the machine when the can is sufficiently filled. In order to have a construe tion that would fulfill. this requirement without the necessity of making use of disks of varying weights l employ means whereby a vforce independent of that exerted by the packed sliver, but cooperating therewith used. Preferably I make use o-f a plurality of compression springs 27 stationed in pock- CII ets 2S drilled in bosses 29 which are integral With the rim of the coiler tube disk. rI`he lower end of each .spring partly abuts against the shoulder 30 on the rim of coiler tube disk and partly on the upper surface of the ring gear flange. The other end of the spring abuts against the underside oit the adjusting plate 3l which is slidably mounted. in slot 32 formed in the upper portion of the boss 29. The adjusting plate is held in position by the adjusting screw 33 threaded into the top of boss 29. To equalize the movement of the adjusting plate in its slot, another compression spring 84 abuts between the adjusting plate and the bottom of a second pocket 35 :t rmed in the boss 29.

By this construction When the springs are relaxed to their full limit the packing sliver in the can is opposed by the entireveight of the coiler tube disk supported on its rim directly on the flange of the ring gear but With the springs under compression part or" the Weight of the disk is absorbed by the springs and the rim of the disk is raised from its seat on the flange of the ring gear with the result that the pressure of the packing sliver against the coiler tube disk is re duced and the can-full stop motion quickly acts to stop the machine before the can overlills With sliver.

I claim:

1. In a machine of' the character specified having a can-full stop-motion, in combination, a pair of sliver calendar rolls, a receptacle for the sliver delivered by said rolls, means located between the calender rolls and top of said receptacle for coiling and packing the sliver in the receptacle, means for simultaneously imparting rotary motion to the receptacle and the coiling and packing means, and means for regulating the amount of pressure exerted for actuating said canf'nll stop-motion.

2. In a machine of the character specified having a can-full stopsmotion, in combina- A'15 tion, a pair of calender rolls, a rotatable rcceptacle for the `sliver delivered by said rolls, a coiler plate located between the calender rolls and the top of said receptacle said plate having a circular opening therein, a ring gear rotatable in bearings concentric with said opening, an inner annular flange at the base of the ring gear, a coiler tuhc disk detachably and loosely mounted on fiange, a plurality of compression sprn coacting between the disk and rire' gear, and a regulating screuv for each spring Whe ij-x the amount of' pressure exerted hy the sliver and said disk against the cairfull stepmotion detector may be varied.

3. In a coiler mechanism, the combination of a coller plate having a circular openly' therein, a ring gear, bearings in tl e coiler plate for said gear concentric with the op ing in the plate, an inner annular fiange at 15- the base of the ring gear, a coller tube dloosely mounted on said flange, and mean.-J for detachably connecting the coiler tube disk and the ring gear.

t. In a coiler mechanism, the combination ofl a coiler plate having a circular open' therein, a. ring gear, bearings in the coiled plate for said gear concentric with the openV ing` in said plate, an inner annular flange the base vof the ring gear, a coiler tube d loosely mounted on said flange, a notch in the rim of said disk, and a pin fixed to the ring gear coacting with said notch for de tachably connecting` the disk and ring gear.

In testimony whereof, I have signed tir.;-

specification.
